"I hope efforts to make the world's best restrooms in Japan
will spread broadly," Haruko Arimura, minister in charge of women's
empowerment -- who is overseeing the project -- said in a recent press
conference.

"It is part of our efforts with hospitality for the (2020 Tokyo) Olympic and Paralympic Games," Arimura said.

Report claims

A 145-page report on improving quality of life claims the
drive towards better bogs will "empower women" because by "improving
comfort, cleanliness and safety, the quality of work and leisure can
improve dramatically."

The report said restrooms are places where women want to
feel secure enough to get changed, brush their teeth, do their make up,
and change their baby's diapers.

It also noted that toilets are not
universally available in some developing nations, and that
poorly-designed facilities in some places can put users -- particularly
women -- at risk of violence or kidnapping.

As well as looking for ideas on how to make environmentally-friendly toilets for use in natural disasters, the competition is asking for ideas on how to make toilets easier for "foreigners and physically disabled people".

A leaflet produced by organisers suggests, for example,
that including easy-to-understand pictograms might help non-Japanese
people with exactly how to use a toilet.

The flier does not specify which part of using a toilet foreigners might have trouble with.

Judging

The competition will be judged by a panel of seven, including architects and an official from the Japan Toilet Association, using five criteria -- cleanliness, safety, comfortableness, novelty/creativity, and sustainability.

Applicants have until the end of the month to submit their designs. Minister Arimura will announce the winners in September.

Toilets in Japan have been raised to something of an art.

Nearly every household and most public restrooms are equipped with a seat that is plugged into the mains electricity.

The bog-standard version simply warms the seat -- an
under-appreciated luxury among the uninitiated -- while top-of-the-range
models offer an array of options, including warm water jets,
blow-dryers, deoderisers and masking sounds.

Young foreign visitors rave about them, filling social
media with pictures of the loos they find in Japan, while a bidet seat
to take home is among the first items on Chinese tourists' shopping
lists.
